After the equation type is selected, [EQN] indicator lights up. The
following equation solve guiding page sample will be shown if you
specified the equation solve for two (2) or three (3) unknowns
simultaneous linear equation:
• For quadratic or cubic equation solve, the coefficient name starts
with "a"
• You cannot input complex number as an coefficient
• The calculation starts after the last factor ("c2": where the
simultaneous linear equations with two unknowns, "d3": where the
simultaneous linear equations with three unknowns, "c": quadratic
equation and "d": cubic equation) of the specified equation and
then the root of an equation appears.
• The input display appears by pressing the key, and you can
display or edit the value by pressing the or key. After that, the
last factor is displayed and a calculation is performed again by
pressing to display the root.
• For quadratic or cubic equation, the Variable name starts with
"X1".
• Press or key to display the equation solve results.
• If you want to return to the coefficient input screen, simply press
key.
